Title: Synthetic control device for transmission shock reduction purpose of power train
Inventor: ISHII SHIGERU
IPC: F16H63/50
Filed: 1988-07-28
Abstract: PURPOSE:To reduce a transmission shock by detecting as if the speed change is carried out with an automatic transmission from the time when the output rotation frequency detecting valve of a prime mover begins to reduce to the time when the suspected speed ratio operation value of a torque converter becomes a set value. CONSTITUTION:When a line pressure learning control device 11 detects that an automatic transmission 3 converts friction elements 4 which are operated by the line pressure 12 and it is carrying out a speed change, by a speed change detecting device 8, the device 11 learning- controls the line pressure 12 during the speed change to make the speed change time to an object value 9. In this case, a suspected speed ratio operation device 7 computes a suspected input rotation frequency by multiplying the output rotation frequency of the automatic transmission 3 detected by a rotation sensor 6 by the gear ratio after the speed change, and computes further the suspected rotation ratio of a torque converter 2 which is the ratio to the output rotation frequency of a prime mover 1 detected by a rotation sensor 5. And the speed change detecting device 8 detects the operation from the starting of reduction of the output rotation frequency of the prime mover 1 to the time when the suspected speed change ratio comes to be a set value as the speed change of an automatic transmission. In such a way, a transmission shock can be reduced securely constantly.

Title: Automatic density regulator
Inventor: NISHIKAWA MASAHARU
IPC: G03G15/08
Filed: 1983-10-08
Abstract: PURPOSE:To enable control of a toner mixing ratio with high accuracy by sampling the photoelectric detection information on the surface of the developer acting to the outside region of an image screen when an electrostatic latent image is not formed and controlling the replenishment of the toner according to the detection signal thereof. CONSTITUTION:A two-component developer consisting of a magnetic carrier and a toner is held and conveyed by magnetic force on a developing roller and is acted to the electrostatic latent image formed on an electric charge holding member. A photoelectric detector is disposed on the dowstream side of the developing part to measure the optical light reflected from the non-tufting part of the developer and to control the replenishment of the toner. Since the photoelectric detection information of not the surface T2 of the region of the image screen corresponding to the electrostatic latent image but the surface T1 of the outside region of the image screen where the electrostatic latent image is not formed is sampled, the toner is not consumed in the place where the detection signal obtainable from the photoelectric detector is generated and therefore an average toner mixing ratio is provided in said place. The stage detection output is thus obtd.

Title: Semiconductor device provided with loading compensation circuit of bus line
Inventor: CHIYOU KENJIYUN
IPC: G11C11/417
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To transmit a signal at high rate by providing a loading compensation means, comprising a pulse generation means and a driving means, at a predetermined position of bus line thereby enhancing the transmission characteristics of bus line. SOLUTION: When a transmission signal IN falls from H to L, a pulse generation circuit 420 generates a positive pulse to conduct an NMOS transistor 432 thus starting discharging operation of signal being applied to a node N3 at high rate. When the transmission signal IN rises from L to H, a pulse generation circuit 410 generates a negative pulse to conduct a PMOS transistor 431 thus feeding a power supply voltage and charging the node N3 at high rate. More specifically, the loading compensation means is actuated when the inverted signal IN makes a transition from H to L or L to H to bring about a normal potential level at the node N3 and minimizes the loss of signal IN.
